EROI means “Energy Returned On energy Invested”.

“The U.S. was producing oil back in the 1930′s at an EROI of 100/1… which means it cost the energy of one barrel of oil to produce 100 barrels for market.In 1970, it fell to 30/1 and today its below 10/1.

SHALE OIL coming out of the mighty Bakken Field has an EROI of 5/1, and all that supposed 1 Trillion barrels of OIL SHALE in the western U.S. (not to be confused with shale oil) has a lousy EROI of 2/1.”

And some fools or demagogues would have that the world, let alone the USA, will be able to keep just burning off oil products in our usual energy-intensive lifestyle for many years to come?

Believe them, and youre lambs wandering into the slaughterhouse.
